NH₃ Sensor Kit

NH₃ sensor kit for use in laboratories, livestock, poultry farms, and sewage treatment plants to monitor the leakage of ammonia gas and give an alarm to protect humans and animals.

NH₃ kit consists of an Aranet 0-10 VDC transmitter with a 0-10 V transmitter with a 24 VDC power supply (box) and a DOL53 Ammonia sensor, as well as relevant details for the sensor and transmitter to be connected.

The cable to connect the transmitter to the mains power is not included.

Assembling the kit

• It is possible to pair the transmitter to the base station with or without the sensor connected.
• To pair the transmitter, the transmitter must be near the base station (max 20 m).
• Pairing the sensor with the battery ensures an interrupted signal to the base station during the whole installation process, as well as connection to the sensor in case of an electricity outage or sensing element failure.
• When installing and placing the sensor, note that the cable must be routed in a manner to obtain a “water/drip loop” for water to drop off. Do not stress the cable.
• If you experience any difficulties, get in touch with [e-mail]

1

Pair the sensor to the base station (using batteries)

• Have the transmitter (lid opened) and 1x AA battery ready.
• Unscrew and take off the transmitter’s lid.
• Open the WebGUI web interface (ensure that you have the latest firmware upgraded).
• Open the section “SENSORS,” and there choose the preferred measurement interval.
• Click the “PAIR SENSOR” button on the computer screen and then immediately insert the batteries or insert batteries and click the “PAIRING” button on the transmitter (left corner).
• The sensor will be paired and appear in the category “SENSORS”.
• You can finish your sensor setup and screw the lid back

Connect the kit to the mains power cable

• Make sure the cable is not connected to the power mains. Unscrew and take off the transmitter’s lid.
• Connect the cable to the transmitter as shown in the scheme below.
• To ensure high IP protection, the cable must be directly connected to mains power.
• After finishing the assembly, tighten the cable glands to ensure water protection.
• Screw back the transmitter’s lid.
